CONTRACTORS ASSOCIATION

Plumbing-Heating-Cooling Contractors - National Association 



FOREWORD 



Since its founding as the National Association of Master Plumbers in 1883, the 
National Association of Plumbing-Heating-Cooling Contractors has maintained 
a serious interest in plumbing standards, codes and good plumbing design 
practices. 

The Association published the NAMP "Standard Plumbing Code" in 1933 and 
furnished revised editions until 1942. NAPHCC participated in the development 
of special standards for wartime plumbing and later was represented on the 
National Plumbing Code Coordinating Committee, whose work ultimately 
resulted in the adoption of A40.8 as a standard or model plumbing code in 
1955. 

NAPHCC served as a sponsor in the early 1960's on the project that attempted 
to update the 1955 document. This project was operated through the 
procedures of the American National Standards Institute. However, the A40.8 
revision project was not completed because consensus could not be achieved. 

In order to provide local and state governments, code administrative bodies and 
industry with a modern, updated code, NAPHCC published the "National 
Standard Plumbing Code" in 1971, following the format and sequence of the 
A40.8 to provide for maximum convenience of users. 

With the June 1973 revision, the American Society of Plumbing Engineers 
joined this effort by co-sponsoring the National Standard Plumbing Code. ASPE 
maintained its co-sponsorship status until September 1980. Upon ASPE's 
withdrawal of co-sponsorship, the Code Committee composition was changed 
to include not only members of the contracting and engineering communities 
but also members of the inspection community. Contractors, engineers and 
inspectors now comprise the National Standard Plumbing Code Committee. 

This document contains the formal and editorial changes accepted by the Code 
Committee during the August 24, 2006 Public Hearing. This document is to be 
used in conjunction with the 2006 Code. 



2007 Supplement to the 2006 NSPC 



NATIONAL STANDARD PLUMBING CODE SUPPLEMENT 

Title: 

National Standard Plumbing Code Supplement 
Scope: 

The development of a recommended code of plumbing practice, 
design, and installation, including the establishment of 
performance criteria predicated on the need for protection of health 
and safety through proper design, installation, and maintenance of 
plumbing systems. This scope excludes the development of specific 
standards related to the composition, dimensions, and/ or 
mechanical and physical properties of materials, fixtures, devices, 
and equipment used or installed in plumbing systems. 

Purpose: 

To provide practices and performance criteria for the protection of 
health and safety through proper design of plumbing systems. 

Exceptions: 

In case of practical difficulty, unnecessary hardship or new 
developments, exceptions to the literal requirements may be 
granted by the authority having jurisdiction to permit the use of 
other devices or methods, but only when it is clearly evident that 
equivalent protection is thereby secured. 



2007 Supplement to the 2006 NSPC

(NSPC pg. 117, Illustrated pg. 221) 

Change Section 10.5.8 Connections to Carbonated Beverage Dispensers to read 

The water supply to a carbonated beverage dispenser shall be protected against backflow 
with an internal backflow preventer conforming to ASSE 1032 1022 or an air gap. 
Carbonated beverage dispensers and carbonated beverage dispensing systems without an 
internal backflow preventer conforming to ASSE 1032 1022 or an air gap shall have the 
water supply protected with a double check valve with atmospheric vent conforming to 
ASSE W33 1022, 

(NSPC pg. 121, Illustrated pg. 228) 

Change Section 10.8.8 Pressure Tanks - Vacuum Relief to read 

All wat e r pressure tanks shall be provided with a vacuum relief valve at the top of the 
tank that will op e rat e up to a maximum water pr e ssur e of 200 psi and to maximum water 
temp e rature of 200°F. The minimum size of such vacuum r e lief valves shall b e 1/2 inch. 

Domestic water pressure tanks shall be provided with vacuum relief if required by 
Section 10. 16 .7 or the tank manufacturer. 

(NSPC pg. 123, Illustrated pg. 232) 

Change Section 10.12.6 Individual Fixture Valves to read 

a, Ina building used or intended to be used for other than dwelling purposes, the water 
distribution pipe to each fixture or other piece of equipment shall be provided with a 
valve or fixture stop to shut off the water to the fixture or to the room in which it is 
located. These valves shall be accessible. Sill cocks and wall hydrants shall be 
separately controlled by a valve inside the building. 

b. Self-piercing and needle-type saddle valves shall be prohibited. 

(NSPC pg. 124, Illustrated pg. 235) 

Change Section 10.14.3 Sizing Water Distribution Piping to read 

a. The supply demand in gallons per minute in the building hot and cold water 
distribution system shall be determined on the basis of the load in terms of water 
supply fixture units (WSFU) as shown in Table 10.14.2A and the relationship 
between the load in WSFU and the supply demand in gallons per minute (gpm GPM) 
as shown in Table 10.14.2B . Refer to Appendix M for a more detailed table of WSFU 
and equivalent GPM . For fixtures having both hot water and cold water connections, 
the separate hot and cold water loads shall be taken as 75% of the listed fixtur e unit 
WSFU value. 

b. Main risers and branches of the water distribution system shall be sized based on the 
minimum available water pressure at the source, any elevation differences between 
the source and the fixtures, pressure losses in the distribution system, and the pressure 
(with flow) required at each connection of the fixture supply branches.

(NSPC pg. 228, Illustrated pg. 386) 

Change Section B.7.4 Step-by-Step Procedure of Simplified Sizing Method to read 

For sizing systems in relatively low buildings, the simplified sizing method consists of 
the following seven steps: 

1. Obtain all information necessary for sizing the system. Such information should be 
obtained from responsible parties and appropriate local authorities recognized as 
sources of the necessary information. (See Section B.2.) 

2. Provide a schematic elevation of the complete water supply system. Show all piping 
connections in proper sequence and all fixture supplies. Identify all fixtures and 
risers by means of appropriate letters, numbers, or combinations thereof. Identify all 
piping conveying water at temperatures above 150°F, and all branch piping to such 
outlets as solenoid valves, pneumatic valves, or quick-closing valves or faucets. 
Provide on the schematic elevation all the necessary information obtained in Step 1. 
(See Section B.2.9.) 

3. Mark on the schematic elevation, for each section of the complete system, the hot and 
cold water loads conveyed thereby in terms of water supply fixture units in 
accordance with Table B.5.2. 

4. Mark on the schematic elevation, adjacent to all fixture unit notations, the demand in 
gallons per minute corresponding to the various fixture unit loads in accordance with 
Table B.5.3. 

5. Mark on the schematic elevation, for appropriate sections of the system, the demand 
in gallons per minute for outlets at which demand is considered continuous, such as 
outlets for watering gardens, irrigating lawns, air conditioning apparatus, refrigeration 
machines, and similar equipment using water at a relatively continuous rate during 
peak demand periods. Add the continuous demand to the demand for intermittently 
used fixtures, and show the total demand at those sections where both types of 
demand occur. (See Section B.5.4.) 

6. Size all individual fixture supply pipes to water outlets in accordance with the 
minimum sizes permitted by regulations. Minimum fixture supply pipe sizes for 
typical plumbing fixtures are given in Table B.5.2. 

7. Size all other parts of the water supply system in accordance with velocity limitations 
recognized as good engineering practice, and with the velocity limitations 
recommended by pipe manufacturers for avoiding accelerated deterioration and 
failure of their products under various conditions of service. (Sizing tables based on 
such velocity limitations and showing permissible loads in terms of water supply 
fixture units for each size and kind of piping material have been provided and may be 
applied in this step.) (See Section B.6.) 



44 200 7 Supplement to the 2006 NSPC 



(NSPC pg. 232, Illustrated pg. 390) 

Change Section B.8.2 Solution to read 

1 . All information necessary to develop the design must be obtained from appropriate 
sources. 

2. After the information is known, the isometric drawing (Figure B.8. 1) is marked up 
with general water supply information, and the mains, risers, and branches are 
suitably identified. 

3. The water supply fixture unit loads are marked on the drawing next to each section of 
the system. These values are obtained Tables B.5.2 and B.5.3. Many designers use 
parentheses marks for WSFU to distinguish them from the gpm values. 

4. The maximum probable demand in gpm is marked on the drawing for each section 
next to the WSFU values. These values are obtained from Table B.5.4, using the 
columns for flush-tank systems. 

5. Where sections of the piping serve more than one hose bibb, each additional hose 
bibb adds a demand of 1.0 WSFU to the piping. Wherever a section of piping serves 
a single hose bibb, it adds 2.5 WSFU. 

6. All individual fixture supply pipes to water outlets are sized on Figure B.8.1 in 
accordance with the minimum sizes shown in Table B.5.2. 

7. All other parts of the system are sized in accordance with the velocity or pressure 
limitations established for this system as the basis of design. Piping is sized in 
accordance with the maximum probable demand for each section of the system. 
Sizing is done using Table B.7.3A through B.7.3H, and specifically the tables dealing 
with Copper Water Tube, Type K for sizing the water service pipe, and with Copper 
Water Tube, Type L, for sizing piping inside the building since these are the materials 
of choice as given in the general information on the drawing.
